Abstract

The present invention provides a complex resonant converter having a synchronous rectification circuit to achieve high power-conversion efficiency, to reduce the circuit scale with simplified circuit, and to have low cost and to provide a winding voltage detection means on the secondary side of the complex resonant converter; the gap length of an insulating converter transformer (PIT) is set to the order of 1.5 mm; the coupling coefficient thereof is set to as small as the order of 0.8; and the number of turns of a primary winding (N1) and those of secondary windings (N2A,N2B) are set such that the induced-voltage level per turn (T) of the secondary windings will be 2V/T. As a result, the magnetic flux density of the core of the insulating converter transformer (PIT) is below a predetermined value, so that the rectified current on the secondary winding side can be placed in a continuous mode even under a heavy-load condition.
